Throughout American history, there have been several large waves of immigration, particularly the inclusion of people of color, which has sparked much controversy in society. Especially with the aging of the white population and the changing marriage and childbearing trends among the younger generation, there has been a profound concern about the future decline in fertility rates. Some extreme viewpoints believe that the prosperity of the nation and the maintenance of social morals can only be ensured by increasing the fertility rates of white males. These ideas even led to some scientific experiments aimed at improving male fertility, despite the radical nature of some of these experiments.

 

Leo Stanley, a prominent doctor in the early 20th century, conducted experiments that not only changed the perception of fertility in America but also inspired future modern medical research. Stanley firmly believed that the superiority of a race influences the future of a nation. In order to improve the fertility of white males, he carried out extremely radical experiments, such as transplanting gorilla testicles into humans. As a doctor, Stanley became the Chief Medical Officer at the California State Prison, where he used the prison environment to carry out these dangerous experiments, collecting a large amount of experimental data through deceit and inducement.

 

Although his attempts did not achieve the expected results, his experiments provided important clues for later research, including the development of modern therapeutic drugs, and even laid the foundation for drugs like Viagra.

 

In recent years, male fertility worldwide has faced severe challenges. Numerous studies have shown that sperm count among men in economically developed countries has drastically declined. According to research from *Human Reproduction Update*, from 1973 to 2011, sperm concentration among men in North America, Europe, and Australia declined by an average of 1.4% per year, while total sperm count in semen decreased by more than 50%. Experts predict that by 2050, half of American men may lose their fertility, which presents a significant challenge to future families.

 

China’s male fertility is also facing similar issues, with significant concerns about the decline in both sperm count and quality. In this context, more and more men are choosing to freeze their sperm as a way to safeguard their future fertility. While male fertility is relatively high over a longer period, the gradual decline with age cannot be ignored. Therefore, sperm freezing, as a means of fertility preservation, has gradually been accepted by more men.

 

Today, with advancements in technology, sperm freezing, sperm thawing, and IVF-PGT have become highly advanced. these technologies are widely applied and are strictly safeguarded by legal and medical regulations. Particularly, IVF in the U.S., Mexico, and Japan has become one of the global leaders in assisted reproductive technology. Not only can men preserve their fertility through sperm freezing, but women can also ensure future fertility opportunities through egg freezing.

 

Dr. Nathan Zhang points out that with societal changes and the general decline in human fertility, more and more families are choosing IVF-PGT and other assisted reproductive technologies to achieve their fertility goals. The U.S. technological and legal system provides more reliable safeguards for this process. Especially for families facing fertility challenges, IVF-PGT undoubtedly provides an effective solution.
